Answer:

x=35

Step-by-step explanation:

60+(4x-20)=180

first you eliminate the brackets.

=60+4x-20=180

(60 and 20 can take away itself because it has no variables... you don't have to rearrange anything ,just simple mental math...60-20=40)

40+4x=180

(Simple algebra time)

(rearrange for better understanding)

4x=180-40

(1.Anything after the equal sign always come first. 2. When bring over the like terms (numbers with no variables) you change the sign...so if the sign is a negative and you're bring it over it'll become positive. There is no sign in front of 40 which means it is positive and so since it is being brought over the sign turns into negative)

4x=140

(Now you have to find the value for x)

x=140/4(140÷4)

x=35

simple demonstration:

60+(4x-20)=180

60+4x-20=180

40+4x=180

4x=180-40

4x=140

x=140/4

x=35
